17 Claims. (Cl. 43112) This application is a continuation-in-part of myapplication Ser. No. 412,113, filed Nov. 18, 1964, and now abandomed, v3 I' This invention relates to lighting devices and is more particularlyconcerned with improvements in a utility light, havingincorporated'therein means for attracting and destroying insects. U u f-Many forms of electric lighting devices have been provided heretoforewhich are used primarily for'illurnination, for example, the ordinarystreet light, which is designed to illuminate a sizable area, patio anddriveway lights, which are usually designed to illuminate a smallerarea, parking lot lights, and the like. Also, various devices have beenprovided which employ light; rays to attract insects so as to trap ordestroy the latter. In the design of such devices, lamps have beenemployed which produce so-called black light, the popular name for nearultra violet energy, which it is'well known attracts practically allnocturnal insects. Although'in a technical sense this is not light sincethe human eye is insensitive to it, it is commonly known as'black lightand the most common sources are black light fluorescent lamps andmercury vapor lamps, both of which are readily available commercially.In devices of this characterlhe lamps have been used simply as a source'of' black light for attracting the insects and usuallythe devices haveincluded "ice imum of debris which is neither unsightly nor distasteful.

Another object of the invention is to provide a utility light of thecharacterdescribed having insect attracting and destroying elementswhich are enclosed in a housing so as to be out of sight and arranged sothat the insects which are attracted have little chance of escapingdestruction and the debris resulting from their destruction which isdischarged from the device is not objectionable.

Still another object of the invention is to provide a utility lighthaving combined therewith insect attracting and destroying featureswhich is constructed so that illumination and insect attraction may beprovided for by either fluorescent light bulbs or a-mercury vapor lampwith a minimum of modification required to convert from the use of onelight source to the other.

some arrangement whereby the insects'attracted by the light are suckedor forced into a collection container and then destroyed. Also, in sonicof these devices an energized grid has been interposed in the path oftravel of the insects so that the latter will be electroe'uted oncontact with the grid. Many such devices'have' been oba insects would becontacted and then fall away from it and escape or others would bekilled and fall to the ground leaving an unsightly and unwanted mess..Where the grid has been openly mounted it has proven to be urisightlyand distasteful in operation and women particularly have objected to thecrackling and sizzling of insects directly before their eyes. 1 Y

A primary object of the present inventionis'to provide a utility lightof improved construction and to incorporate therein a means forattracting and destroying insects which lacks the objectionable featuresusually found in prior devices provided for this purpose.

A further object of the invention is to provide a utility light havingcombined therewith insect'attracing and destroying elements which arehidden from view and which are more eifective in attracting anddestroying-insects than any previous devices of a similar character.

A more specific object of the invention is to provide an improvedutility light having combined therewith a means for-attracting anddestroying insects wherein the light is adapted to provide adequateillumination for normal utility light purposes, such as illumination ofstreets, parking lots, patios and the like, while at the same time it ishighly effective in attracting undesirable insects and destroying thesame so as to produce a minutility light and insect destroying device;

A still further object of the invention'is'to provide a utility lighthaving incorporated therein an insect destroying device which includesan electric grid and a suction fan for forcing the insects against thegrid, with the fan being mounted in an inverted bell-shaped 'o-rificewhich provides a venturi effect and serves to reduce the centrifugalforce generated by the rotation of the fan so that the insects do notaccumulate on the housing ad jacent the fan blade tips which otherwisewould occur and interfere with the movement of the air or clog theorifice so as to stop theoperation of thefan;

Another object of the invention is toprovide a combination utility lightand insect attracting and destroying device'which' incorporates thereinan improved electrical grid which is effective for destroying hardshell' insects which are not readily incinerated. A further object ofthe invention is to provide a utility light of the character describedwhich is sturdy' in construction, completely'safe in useand which willwithstand the -effects of weather. I t

These and other object'sand advantagesiof the invention will be apparentfrom a consideration of tlie'several forms of utility light whichareshoiw'n by way of illustration in the accompanying drawings wherein:.FIGURE 1 is a perspective view of a'utility light having combinedtherewith means for attracting and destroying insects which embodies theprincipal features of the invention; FIGURE 2 is a sectional view takensubstantially on I the line 2'2 of FIGURE 1;

FIGURE 3 is asectional viewtaken on'th'e line 3 3 of FIGURE 2; I I iFIGURE 4 is a sectional view taken on theline' 4-4 ofFIGURE 2; FIGURE 5'is a sectional view, similar to FIGURE 2, showing a modified form of theutility light in which a mercury vapor lamp is employed'as a light:producing source;

FIGURE 6 is 'a sectional view, similar to FIGURE 2 showing afurthermodification form 'of the combination FIGURE 7 is across sectiontaken on the line 7 -7 of FIGURE 6; and

FIGURE 8 is a fragmentary section taken on the line 88 of FIGURE 7, to alarger scale. Referring to' FIGURES 1 "and 2 of the drawings, there isillustrated autility light 10 which comprises a canopyforming topsection 11, an intermediate lamp or light bulb supporting section 12,and an insect destroying bottom section- 13.

; rality of openings 16 for air circulation. The two members 14 and 15are joined at their periphery and form a hollow canopy which is hingedat '18 to a ring member 19 forming the uppermost portion of the bulbsupporting section 12. The ring member 19 is normally seated in theoutermost portion of an inwardly recessed section 20 in the center ofthe lowermost top member 15 when the top 11 is in normal closedposition.

The intermediate section 12 comprises a center cylindrical tube member21 which forms a lamp or bulb supporting column and which may be asection of extruded aluminum tubing or similar rigid material. Thesupporting column 21 is stabilized at its top by a depending cylindricalextension 22 in the center of the bottom member 15 of the top section 11when the latter is in closed position which extension 22 is apertured topermit the flow of air down through the column 21. At its bottom end thecolumn 21 fits over a cylindrical flange 23 upstanding on a spider 25which is fitted in the top opening of a hollow housing 26, the latterforming the main body of the insect destroying bottom section 13 of thedevice.

The column forming cylindrical tube member 21 serves as a support for aplurality of circular fluorescent lamp bulbs 27 which are arranged inhorizontal planes and spaced vertically around the tube member 21. Thelamp bulbs 27 are secured in place by a plurality of holders 28 whichare in the form of spring loops affording a limited degree offlexibility. The lamp bulbs 27 are also supported to some extent byleads 30 which connect each bulb with a transformer 31 mounted on theinside wall of the tube member 21. A protective cage 32 su-rrounds thelamp bulbs 27 and is formed by peripherally spaced, vertical rods 33having their upper ends seated in threaded relation in suitableapertures 34 provided in circumferentially spaced relation in the topring member 19. The vertical rods 33 have their lower ends seated insocket forming apertures 35 in the top rim form ing portion 36 of thebottom housing 26. The vertical rods 33 are connected together by aplurality of concentric ring members 37 which are vertically spacedalong the outside of the rods 33 and are brazed or otherwise securedthereto. The vertical rods 33 may be secured in any desired manner inthe sockets 35 so as to permit ready separation of the cage from thehousing 26.

The insect destroying bottom section 13 of the device comprises thehousing forming member or outside casing 26 which has a verticallyextending bottom socket formation 38 enabling the device to be securedon the top of a supporting post or column 40. The socket formation 38 isconnected to the vertical side walls of the casing 26 by radiantlyextending web formations 41 (FIGURE 4) which may be a plurality of thinvertical plates. At the upper end of the casing 26 a fan assembly 42 issupported on the spider 25, the latter being mounted in the top of thecasing on an inwardly extending annular flange or rib 43. The fanassembly 42 is mounted so that the fan blades 44 rotate in a plane belowthe spider 25 and in an orifice or throat formed by an invertedbell-shaped member 45 which is also supported on the annular rib 43. Thecurved annular flange forming member 45 has a downwardly extendingmarginal portion 46 which is spaced a relatively small distance outsidethe path of the tips of the fan blades 44 and which is adapted tocooperate with the fan blades 44 in producing a venturi effect, so thatinsect laden air which is sucked down past the lamp supporting cylinder21 flows freely through the orifice formed by member 45 and drives theinsects against a horizontally disposed electric grid 47 mounted inspaced relation below the fan blades 44. A transformer 48 for the grid47 is mounted in the bottom of the housing 26 and completes theassembly.

The transformers 31 for the light bulbs, the motor for the fan assembly42, and the transformer 48 for the grid are wired in an appropriatemanner with a suitable connection for plugging into an electric supplyline. Means is provided for disconnecting the grid and the fan from thecurrent supply so as to permit the light to be used solely forillumination.

When in use, the light is set up in the area in which illumination andinsect elimination is desired. When connected to a suitable source ofelectric power, the light bulbs 27 will provide adequate illumination,with the bottom face of the top member 15 and the lamp column 21 servingas a reflector for the lamps. A mixture of ordinary fluorescent bulbsand black light producing fluorescent bulbs may be employed, the ratiobeing dependent upon the desired amount of illumination. Insects areattracted by the black light rays and drawn by the suction created bythe fan blade 44 through the spider 25 and the orifice forming member 45and propelled against the grid 47 where they are cremated with theresultant waste or ash, which will be a minimum amount per insect,falling between the bars of the grid 47 and out of the bottom of thecasing 26 between the vertical bottom webs 4 1. The throat or orificearrangement created by the bell-shaped member 45 provides a venturieffect which greatly reduces the tendency of the insects to be thrownout by the centrifugal force created by the fan blades 44 and preventsany undesirable pile-up of the insects adjacent the tips of the blades44. The fan blades 44 draw air through the top section 11 and downthrough the lamp supporting tube or cylinder 21 which not only serves tocool the transformers 31 and prevent overheating of the same but alsoadds to the volume of air flowing through the restricted opening ororifice defined by the member 45 and insures that all the insects willbe projected against the grid 47. The horizontally disposed grid 47 isrigidly mounted and the electrodes are relatively short so that thespaces between the same may be made rather small without danger of theelectrodes being thrown together and short circuited by jolting orjarring the device. This insures that practically all insects regardlessof their size will be electrocuted and destroyed, the larger insectsbeing held on the grill 47 until reduced to an unobjectionable ash whichwill fall out of the bot tom of the casing 26 with the help of the airflow produced by the fan blades 44.

Referring to FIGURE 5, there is illustrated a .form of the device whichis adapted to utilize a mercury vapor lamp bulb for illumination andinsect attraction. Also, this modification, indicated at 50, illustratesthe ease with which the device of FIGURE 1 may be converted forutilizing another type of illumination and black light producing lampbulb is place of the fluorescent lamps. In this form there is a topcanopy forming section 51 which is slightly modified, an intermediatelamp supporting section 52 which is also modified and a bottom insectdestroying section 53 of the same construction as the correspondingbottom section shown at 13 in FIGURES 1 and 2. The canopy forming topsection 51 is constructed as shown in FIGURES 1 and 2 with a dishshapedtop member 54 connected at its periphery with a bottom member 55. Thecenter portion of the bottom member 55 has an opening 56 defined by adepending annular flange 57 which is adapted to fit into the top end ofa vertically disposed bulb enclosing member 58 which in this form of thelight is of truncated cone shape and of transparent or translucentmaterial so as to utilize fully the illumination provided by the mercurylamp bulb 60 which is supported in a socket 61 at the top of thecylindrical member 58. The lamp socket 61 and an accompanyingtransformer 62 may be supported by suitable brackets (not shown) in thetop section 51 or the intermediate section 52. The lamp enclosing member58 is telescoped at its bottom end over an upstanding flange 63 in thecenter of a spider 64 supporting the fan assembly 65 in the top of thebottom housing or casing 66. The outside cage which comprises verticalwire rods or "bars 67 connected by spaced horizontal rings 68 of thesame material provides additional protection against breakage for theglobe or chimney forming cylindrical member 58 and the mercury lamp 60and supports the top section 51 which is hinged at 69 to the top ring 70thereof. The spider support 64 for the fan assembly 65 is mounted on theannular flange 71 in the casing 66 which also supports the invertedbell-shaped member 72 forming an orifice or throat in which the fanblades 73 rotate. A horizontally disposed grid '74 and associatedtransformer 75 are mounted in the casing 66 which is of the sameconstruction as in the form of the device in FIGURES 1 to 4. Otherdetails of this form of the device which are not described are the sameas described with respect to the device of FIGURES 1 to 4 and it isadapted to be used in an identical manner.

A further modification of the light is illustrated in FIGURES 6 to 8.The light 80 which is illustrated comprises the top section 81, the lampsection 82 and the insect destroying section 83 which are arrangedvertically in the order named, the general arrangement being the same asin the forms of the light previously described.

The top section or canopy 81 comprises the upper dish-shaped imperforatemember 84 which is joined at its marginal edges to the lower dish-shapedmember 85, the latter having holes or perforations in at least thecenter area thereof for circulation of air. An annular reinforcing ring86 of smaller diameter is secured in the outer margin of a recessedportion 87 of the bottom member 85 and connected by a hinge -88 to anannular ring 89 of the same diameter forming the top member of the cage90 which forms the outer portion of the lamp section 82. The diameter ofthe top section 81 is substantially greater than the diameter of thelamp section 82 and the portion of the lower face of the top section 81which overhangs the lamp section 82 forms a reflector for the lightrays.

The lamp section 82 comprises a center cylinder 91 on which there ismounted in the same manner as in the device shown in FIGURES 1 and 2 aplurality of circular fluorescent light bulbs 92 with associatedtransformers 93 being mounted on the inside Wall of the cylinder 91Which forms a compartment for housing the transformers. The open top ofthe cylinder 91 is adapted to receive an extension 94 formed in thebottom member 85 of the top section 81, which extension 94 is aperturedto permit the flow of air down through the light column 91. Thecylindrical member 91 is telescoped over an upstanding flange formation95 on a fan supporting spider 96 in the top of the insect destroyingsection 83 which flange is spaced inwardly of the outer wall of thesection '83. The cylinder 91 may be removably secured to the spider by aset screw or any approprate fastening element. The outer cage 90comprises circumferentially spaced, Vertically spaced bars 98 andconnecting vertically spaced ring members 99 with the vertical barsconnected at the top to ring 89 and removably connected at the bottom tothe top edge of housing member 97.

The insect destroying section 83 comprises the housing forming member 97having an inwardly extending annular shoulder or rib 100 for supportingthe fan mounting spider 96 and an inverted bell-shaped orifice or throatforming member 101. The fan assembly 102 is supported oncircumferentially spaced radial ribs 103 in the spider 96 and the latteris apertured in the area below the light bulbs 92 and between the outerwall of the cylinder 91 and the outer wall of the housing 97 so as toprovide for passage of air into the compartment formed by the housing97. The fan assembly 102 is arranged so that the blades 104 arepositioned in the orifice formed by the member 101 in the same manner asin FIGURES l and 2. An electrical grid 105 (FIGURES 6 to 8) of specialconstruction is spaced below the fan blades 104 and extends about thetransformer 106 which is mounted in the center of the housing 97 andabove the socket formation 107 provided for receiving a supporting post108. The socket formation 107 is joined to the inner walls of thehousing 97 by a plurality of radially extending ribs 110. The grid has aconical shape as shown with a center opening 111 of greater diameterthan the transformer 106 so as to provide for passage of insect debrisWhich is not reduced to ash form and which is too large to pass betweenthe concentrically arranged circular bars 112 which form the electrodesof the grid and which are supported on connecting radial arms 113extending from the transformer 106. The grid 105 is cone-shaped so thatit acts after the fashion of a funnel and large insects such as beetleshaving a hard shell which is not reduced to ash by the electrodes willslide down the inside surface and pass through the center opening 111.Smaller insects will, of course, be cremated and reduced to anunobjectionable ash as in the form of the grid heretofore described. Thelarger insects will be held on the sloping inner surface of the grid asuflicient length of time for cremation and reduction toanunobjectionable ash which will pass through the grid bars with the helpof the air current created by the fan blades 104 while any hard bodydrawn into the air stream by the suction effect of the fan blades 104will tumble or slide down the sloping surface of the grid and passthrough the opening 111 for discharge from the bottom of the housing'9'7between the raidial ribs 110.

The modified form of the device which is shown in FIGURES 6 to 8 may, ofcourse, be converted to the use of a mercury lamp bulb in the samemanner as in the modification shown in FIGURE 5.

In all forms of the device the canopy formingto'p'section which is ofgreater diameter than the lamp holding section is hinged to the lampholding section so as to form in the closed position a protective coverand partial reflector over the lamp and insect destroying assemblies. Atthe same time, the cover section may be readily swung open for servicingor replacement of light bulbs, transformers, fan assembly and otherelements in the lamp holding and insect destroying sections of thedevice. If desired, a suitable lock or latch may be added to hold thetop section in the closed position. Also, in all forms of the device atransparent or translucent shield of plastic or similar sheet materialmay be provided for insertion immediately within the protective cagewhich extends about the lamp holding or enclosing center cylindermember. The fan blades are, in all forms of the-device, mounted withinan' orifice or throat forming, inverted bell-shaped or frusto-conicalmember which produces a venturi effect on the air stream resulting fromthe operation of the fan and eliminates any pile-up of insects at theends of the fan blades. The insects are driven onto the grid which iseither horizontal or funnel-shaped so as to insure that the insects willbe cremated and reduced to an inoffensive ash which the air streaminsures will be discharged from the device.

While particular materials and specific'details of construction havebeen referred to in describing the several forms of the device which areillustrated, it will be understood that other materials and equivalentstructural details may be resorted to within the spirit of theinvention;
